Magnitudes more accurate than the simple polls relied on by news organizations. As data gathering isn't slowing down any time soon, this will be even more visible in the next elections. A disruptive change. Very exciting.

All debates aside, he correctly predicted all 50 states. Data gathering is still in its early stages, and will keep on evolving along with the mathematical algorithms that make sense of it. I wouldn't be surprised if predictions get close to a 100% on the neighborhood level by 2024.
